Answer:To find the equation of the line that passes through the points (10, 3) and (7, 9), we can use the slope-intercept form of a line, which is given by the equation y = mx + b. In this form, m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
To find the slope of the line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates of the two points, we get:
m = (9 - 3) / (7 - 10)
Simplifying, we get:
m = 6 / -3
So the slope of the line is -2.
To find the y-intercept, we can use one of the given points and substitute the values for x and y into the equation y = mx + b. For example, we can use the point (10,3):
3 = -2(10) + b
Solving for b, we get:
b = 23
So the equation of the line that passes through the points (10, 3) and (7, 9) is:
y = -2x + 23
This is the final answer.
